Описание

An MCP server for calculating carbon footprints from bank statements using EPA GHG emission factors.

README

An MCP (Model Context Protocol) server for calculating organizational carbon footprints from bank statements, financial exports, and structured activity data using EPA GHG emission factors.

Privacy and security first

Runs 100% locally on your machine or server

Sends no financial data to external APIs or cloud providers

Stores no data by default

Exposes read-only calculation and reporting tools

Works with Claude Desktop, Cursor, and other MCP clients

Why This Exists

If you are preparing ESG reporting, investor diligence materials, or internal sustainability reviews, getting to a usable emissions baseline is usually slow and manual.

This server helps turn raw bank statements, Xero or QBO exports, and structured operational inputs into a carbon footprint report in minutes. It maps activities to EPA-aligned emission factors and produces both HTML and Markdown outputs.

The user experience is designed to work for organizations in any country, while the current electricity benchmarking still uses EPA eGRID regional factors under the hood.

What It Does

Ingests bank CSVs, Xero or QBO exports, and structured activity data.
Helps categorize transactions into likely emission sources such as electricity, fuel, travel, shipping, and waste.
Computes Scope 1, Scope 2, and Scope 3 emissions using EPA GHG emission factors.
Scores carbon intensity by revenue and headcount when those inputs are provided.
Generates polished HTML and Markdown reports.

Emission Factor Source

All emission factors are based on the EPA GHG Emission Factors Hub (January 2025), including eGRID 2023 electricity factors and IPCC AR5 global warming potentials.

Covered categories include stationary combustion, mobile combustion, electricity, steam or heat, transportation, waste disposal, business travel, employee commuting, and refrigerants.

Installation

Claude Desktop

Install uv.
Open Claude Desktop settings and edit the MCP config.
Add this server:

{
  "mcpServers": {
    "carbon-footprint": {
      "command": "uvx",
      "args": ["carbon-footprint-mcp"]
    }
  }
}

Restart Claude Desktop.

Claude Code or Cursor

claude mcp add carbon-footprint -- uvx carbon-footprint-mcp

Local Development

git clone https://github.com/MayankTalwar0/carbon-footprint-mcp.git
cd carbon-footprint-mcp
pip install -e .
carbon-footprint-mcp

Available MCP Tools

Tool	Description
`computeEmissions(inputs_json)`	Computes GHG emissions from structured activity data across all 3 scopes.
`generateEmissionsReport(emissions_json, output_dir)`	Renders a polished HTML and Markdown report and saves it to disk.
`listEmissionFactors(category)`	Lists available fuel, eGRID, and waste emission factors.

Supported Emission Categories

Scope	Category	Input Required
1	Stationary Combustion	Fuel type and quantity
1	Mobile Combustion	Fuel type and gallons
1	Refrigerant Leakage	Gas type, leaked kg, and GWP
2	Purchased Electricity	kWh and eGRID subregion
2	Purchased Steam or Heat	mmBtu
3	Transportation and Distribution	Vehicle type and distance
3	Waste Disposal	Material, short tons, and disposal method
3	Business Travel	Travel mode and passenger-miles
3	Employee Commuting	Commute mode and passenger-miles

Carbon Intensity Scoring

Score	tCO2e per $1M Revenue	Interpretation
Excellent	< 5	Best-in-class for low-footprint operations
Good	5-20	Low intensity
Moderate	20-100	Typical for services and tech
High	100-500	Heavy operations
Very High	> 500	Very high intensity
